IMPRQVEMENT IN FOLDING-CHAIRS.

Specification forming part of Letters Patent No. 128,767, dated July 9,1872.

SPECIFICATION.

Be it known that I,PLATT B.V1ELE,- of Rochester, in the county of Monroeand State of New York, have invented certain Improvements inFolding-Chairs, of which the following is a specification: 1

The object of my invention is to provide a cheap simple folding-chairwith a cane or a board seat, that may be upholstered, if desired; and itconsists in hinging the rear of the seat-frame to the back, and couplingthe short posts to the long ones by means of straps or links, pivoted toeach at such points, with .relation to the points of connection of theseat-frame to the legs as to permit the chair to unfold to the desiredposition, and to close so compactly that the short legs and seat, bothof which are straight or nearly so, shall coincide with the straightportion of the long posts or back. V

Figure 1 represents a side elevation of my improved chair, the dottedlines indicating the relative position of the parts when the chair isfolded. Fig. 2 is a front elevation, showing the same when folded. Figs.3 andet show different modifications of the method of coupling the shortlegs and the seat to the back.

The frame A and seat S may be of any desired form or style; the shortlegs a being,

preferably, straight. I use the same kind of axial tie-rod, r, set forthin mypatent of May 7,1872, .but I hang the short postsaupon the outsideof the back posts I). By this relative arrangement of the posts I amenabled to widen the front of the seat S, which greatly improves theform and appearance of the chair. The seat-frame or plank S, whicheveris used, may be pivot-ed between the back posts b, as shown in Fig. 1,or it may be hinged to them either as shown in Fig. 3 or in Fig. 4. The

hanger or coupling straps s are connected to the short legs a by one endbeing pivoted upon the rod 1*, and the other end to the back posts b ata point at such a distance from the point of connection of the seat S aswill cause the chair to maintain the desired position when in use, andalso to permit it to fold closely. This is readily determined by markingthe point when the posts are folded up.

It will be seen that an ordinary cane-seat frame may be used in thischair, ora plank seat may be used; and in either case they may beupholstered, if desired.

What I claim as my invention is- The folding-chair having a rigid orstiff seat,

S, and provided with pivoted links or coupling-straps s, for the purposeof connecting the short legs a to the back posts I), combinedsubstantially as shown and'described, and for the purposes set forth.
